But despite their inevitable departure appearing on the horizon, the sport looks to be in safe hands as several of the world's most promising stars shone for their teams across Europe's top leagues this weekend.

Some of the best performances came from Joao Felix, Kai Havertz and precocious 16-year-old talent Eduardo Camavinga.

Angolan teenager Camavinga -- appearing in only his 10th senior game for Ligue 1 side Rennes -- played a starring role in the victory over powerhouse Paris Saint-Germain, assisting for Romain Del Castillo to head home to winner.

After a few breakthrough games last season, his performances this term have really started to turn heads as Rennes narrowly lost to PSG in the Champions' Trophy and opened its Ligue 1 campaign with back-to-back wins.

Camavinga was born in Angola and moved to France at the age of two, reports L'Equipe. He was spotted by Rennes playing football in Fougères, 50 kilometers from the city, at the age of 13.

Camavinga has already starred against PSG once this season in the Champions Cup defeat.

"Exposed, because if he repeats the kind of performance that he achieved against Montpellier (1-0 on the opening day), he has chances to take a greater place in the team," Stephan explained.

"But also protected, because he is not yet seventeen years old, he is still building himself on a muscular level and he has not experienced a Ligue 1 sequence of matches with the intensity it requires yet."

Camavinga was on the receiving end of several cynical fouls from frustrated PSG players -- many of who cost tens of million of dollars -- who rarely got anywhere near the ball when it was at his feet.

Eduardo Camavinga, remember the name 🙌

The 16-year-old put on a stunning display against PSG last night, including this utterly sublime assist for the winner!

Atleti's new signing Kieran Trippier crossed for Alvaro Morata to head home the opening goal, before Felix's trickery -- a run which started with a nutmeg inside his own half -- won a penalty in the second period.

Morata failed to convert but Atletico held on for victory at the first attempt in the post-Antoine Griezmann era.

Kai shines for Bayer

Bayer Leverkusen star Kai Havertz is by now accustomed to breaking records.

In 2016 he became the youngest debutant in Bundesliga history; in 2018 he became the youngest player to make 50 Bundesliga appearances; and last season he hit 17 goals to become the highest scoring teenager in a Bundesliga season.

After narrowly missing out on the German player of the year award to Marco Reus, reports suggested several of Europe's major clubs would try and prize Bayer's star possession away.
